1.4 External Interfaces
●
Serial Interface
Use applicable cables for wiring and recommended ferrules (made by IDEC, Weidmüller or Phoenix Contact) as
follows.
Using RS422/485 interface
HG2J-7U is not equipped with terminating resistor. Insert a terminating resistor of an appropriate value (about 100 to
120 Ohm, 1/2 W minimum) between terminal number 8 (RDA) and terminal number 9 (RDB), if necessary.
*1 Strip the sheath of the wire 8 to 9 mm from the end.
CAUTION
•
Make sure to turn off the power to the HG2J-7U before wiring each interface.
• The serial interface (COM) can be used as the RS232C and RS422/485 interfaces at same time.
•
Use the SELV (Safety Extra-Low Voltage) circuit to connect the Serial, USB and Ethernet
interfaces.
